Sustainability is at the core of the design. Lush greenery (small trees, shrubs, flowers) is placed on three elevated, cascading walkways, creating an internal valley. The trees and the building’s elements provide shade in the summer. Vegetation also isolates from wind and noise, it captures dust particles and CO2, produces oxygen, and humidifies the air. It also has a positive ­psychological impact on people. A water reservoir placed inside the valley has similar effects – it also moderates the temperature around it (cooling it in summer and making it milder in the winter). All those combined create a different microclimate inside the building – with milder temperatures and cleaner air.

Each of the three elevated slabs has a path ­circumventing the whole story. On both sides of the path, there are rows of vegetation. Along the paths, there are wooden benches, giving a place to pause and enjoy the surroundings. The last level doubles as a viewing platform, offering 360° panoramic views of the ­surroundings. Vertically the slabs are connected via four staircases and two lifts. They are placed at 7 ­meters vertical intervals (the whole structure is 21 meters high).

The ground floor is divided into two parts via the central road – an extension of the planned street going through Europaquartier. On the south-east side, there is a water reservoir, while on the north-west side a small plaza, placed between
